1. Locate the exact position of the rudder stock center on the mold surface.
2. Carefully drill a hole perpendicular to the surface large enough for the plug bolt/bushing.

1. Prepare the liner for lay-up by roughing up the outer surfaces with a grinder and wipe clean with thinner.
2. Screw the UHMW plug into the liner until the bottoms are flush.
3. Mask the top of the assembly to protect it from overspray/excess resin.
4. Locate the assembly against the mold surface and bolt in place through the mold hole.

1. Begin the hull lay-up in normal manner.
2. Cut an X in the cloth above the liner so that it can be laid down and around the flange base with tabs against the outer wall of the liner.
3. On subsequent layers, stagger the position of the X cuts so that the tabs overlap each other.
4. Taper the lay-up to the liner step.
5. BEFORE DE-MOLDING, REMOVE THE PLUG BOLT. (Leave the plug in place until the time of rudder installation.)

1. Remove the UHMW plug from the liner.
2. Inspect the interior shoulder of the liner. Be sure it is clean and free from dust/debris.
3. Confirm that the "O" ring under the shoulder of the TYPE-D Bearing is in place. Add a bead of marine sealant (such as LifeCaulk® or 3M® 101) to this area.
4. Thread the Type-D Bearing/Seal into the liner until the bottom is flush with the hull, compressing the "O" ring.

 

Installation Types

    The procedure for modifying the mold and installing the liner pre-layup differs according to the type of hull being produced. The following are the three most common variations. Click the name or drawing for the Product Installation.

	TYPE ONE- Molds with an existing "flat" at the rudder port location which will use the standard flange type liner.
	TYPE TWO- Molds which require modification to achieve a "flat" surface or pocket for mounting a standard flange type liner.
	TYPE THREE- Molds which require modification to accept an angled liner to match deadrise and rocker angles.
